Dragon's Lair was opened in 1998 for the zoo's three Komodo dragons, and includes outdoor and indoor areas, allowing them to stay warm during the cool winter months. A new animal hospital was also finished in 1998, with separate holding and quarantine wings built on opposite ends of the building. The sick wing separates sick or injured animals from others and allows for proper recovery time. The quarantine wing is used for newly acquired animals, which are quarantined for at least 30 days upon arrival at the zoo before being introduced to their new homes. On September 18, 1998, two plaques were dedicated in memory of musician Jeff Buckley in the Memphis Zoo's Sumatran tiger exhibit. His mother chose that location because of his great love of the Memphis Zoo and the tigers in particular. Jeff frequently visited the zoo, had plans to become a volunteer in 1997 and, according to his mother, never left the zoo without visiting the Butterflies: In Living Color exhibit, which also opened early in 1998. The exhibit was replaced by "Birds and Bees" in late May, 2009.
